Ukrainian Social Democratic Labor Party

The Ukrainian Social Democratic Labor Party (USDLP) was a social democratic political party in Ukraine that was active from 1905 to 1950. The USDLP was party was reformed at the Second Congress of the Russian Social Democratic Labor Party, and it sought recognition as the sole representative of the Ukrainian proletariat. The party became rivals with the RSDLP's successor, the Bolsheviks, as the USDLP sought independence for Ukraine rather than the creation of the Soviet Union. The USDLP worked closely with the Jewish Bund and other factions of Mensheviks, and the party adopted the Erfurt Program of the Social Democratic Party of Germany as its program. After the February Revolution of 1917, the USDLP was the main party in the first Ukrainian government. In 1920, the communist faction of the USDLP split from the party, and the USDLP was forced into exile during Ukraine's war with the Russian SFSR. The party operated in Czechoslovakia, Poland, Germany, and France, and the party existed in exile until 1950.
